Still using wearable equipment to measure human data?

Measurements of human physical signs are becoming standard for wearable devices. Can we have a better choice besides wearable equipment?

MIT's computer science and Artificial Intelligence Research Lab (CSAIL) has invented a new technology that uses the most common Wi-Fi signals to monitor the takeoff and the heart rate of the human chest, even if the wall can accurately monitor the heart rate. According to MIT researchers, the technology is 99% accurate and can track four people at the same time.

All along, tracking the human heart rate data must rely on a certain equipment, if the MIT technology can be popularized, will likely bring a great impact on wearable equipment, the future is likely to need no equipment, we can monitor their physical signs data. In fact, this technology is likely to play a role in the search and rescue of post-disaster personnel. MIT researchers are also considering expanding the system to track human emotions based on measuring human respiration and heart rate.
